Full Fabric Soft Switches

soft_switch

When we created our backpack strap WiFi detector for Engadget, we embedded soft switches to control the device. They used two sheets of aluminum foil separated by a layer of foam with holes punched in it. [Plusea] has taken a similar approach but has replaced the aluminum foil with conductive fabric. The end result is a set of three soft buttons that can be easily washed. Have a look at the video of it in action below. Check out the followup project that uses the buttons to replace a scroll wheel. Continue reading “Full Fabric Soft Switches”

Functional Etch A Sketch Costume

We love all of the creative Halloween costumes that have started trickling in now that the holiday is finally over, and people have found time to document their last minute projects. Take this functional Etch A Sketch costume made by [mazinbenny]. The knobs are lawnmower wheels. The pulley system is strung with 1/16″ wire rope to move a carrier for a dry erase marker. The marker draws directly on an acrylic screen. HowStuffWorks has a post on how a real aluminum powder based Etch A Sketch works.

We’ve covered more technical Etch A Sketch projects in the past. We’ve seen them hooked up to computer mice, drawing portraits at Maker Faire, and commenters have even suggested turning mechanical dry erase boards into giant Etch A Sketches.

A Very Power Suit Halloween


We spent our Halloween dressed as an irate traveler as we flew cross country, but it looks like a lot of people were having much more fun. [flaming_pele!]’s Aliens power loader is one of the best costumes we’ve seen yet. He built it by referencing a 1/12th model kit and a lot of photos. The final costume is about 80% full size which gets it under their 8 foot ceilings. There’s a video of the suit embedded below. Our love of power suits was documented fairly well in our roundup post this summer. Make found two other related costumes: a Star Wars AT-ST and a generic mech constructed from packing foam. Did any of you dress as something truly nerdy for Halloween? Continue reading “A Very Power Suit Halloween”

Coin Slot Detector


Wow, how quickly the wearable electronics world has slid into the gutter. They’re now resigned to watching our nations finest natural resource, the butt crack. This project by [semiotech] uses a LilyPad Arduino to monitor the exposure of the wearer’s coin slot. It detects the presence of light with a photoresistor and alerts the user with the vibrations of a pager motor. This breakthrough in coin slot technology will prevent dryness and certainly reduce our exposure to domestic terrorism. We see plenty of room for future development; the Arduino is already capable of logging exactly how often your coin slot is exposed. Even if you feel this is more protection than your coin slot needs, we recommend Neutrogena’s Coin Slot Cream for general upkeep.

Motorcycle Visor Rain Disk

[andrew] sent us this proof of concept. Based off of the Spiech Clear view screen, used in marine applications, it uses a spinning disk to keep a part of your vision free of water droplets. While you may not be too impressed by watching the video initially, keep in mind that this was a quick prototype. With some planning and a little work, this could be moved to a more convenient location and run by a side mounted motor. It could even be made to be removable for fair weather. It probably doesn’t do so well with mud though.

Mini-POV Hat

Viddy yourself this Halloween standing out amongst your droogs with this Mini-POV bowler. We’ll quit with the nadsat so as to avoid a kick to the yarbles, you have our sincerest appy polly loggy for starting in the first place. [cheeto4493] modified a Mini-POV to sit atop the bowler with an extension hanging out toward the brim that houses the lights. A motor, mounted inside the hat spins the entire device. Some counterweight was necessary to keep the whole thing from wobbling too much.

It is worth noting that, in person, the message scrolls slowly by. The refresh rate on the camera causes it to seem to jump around in the video.

Hydroelectric Power In Your Shoes

All comments on style aside, these are pretty cool. They are power generating shoes, that use water and a small turbine. As you step down, the water is forced through the turbine and recirculated back to the reservoir when you lift your foot. It may not change the world, but is definitely interesting. This reminds us of those shoes that we used to pump up til they burst.
